The decades-old mystery of bis­(di­ethyl ether)tungsten(IV) chloride solved

Several decades after the bis­(diethyl etherate) of tungsten(IV) chloride was first mentioned in the literature, it has now at last been structurally characterized by single-crystal X-ray diffraction analysis, finally confirming its composition.

Crystal structure refinements of stoichiometric Ni₃Se₂ and NiSe

Single-crystal X-ray diffraction investigation of the single-domain structures of stoichiometric Ni₃Se₂ and NiSe are reported.

Variants of the X-phase in the Mn–Co–Ge system

The ordering of two new variants of the X-phase derived from the Mn–Co–Ge system is com­pared with other members of the X-phase family and shows that the degree of disordering depends on the chemical com­position. No com­pletely ordered variants of the X-phase have yet been reported.

A 35-year-old mystery solved: a facile synthetic route and structural confirmation of tetra­chloro­bis­(di­ethyl ether)tungsten(IV)

The existence of the bis­(diethyl ether) adduct of WCl₄ has been confirmed. Room-temperature X-ray diffraction studies of the adduct reveal two coordinated diethyl ether mol­ecules and establish the identity of the com­plex as trans-WCl₄(Et₂O)₂.

Structural differences/similarities of diastereotopic groups in three new chiral phos­pho­ramides

The structural characteristics of diastereotopic groups were analyzed in three new single-enanti­omer phos­pho­ramide structures.
